Damaged blades
Should the blade, in spite of all precautions, come
into contact with an obstruction, shut down the en-
gine immediately and pull the spark plug boot. Tip
the lawn mower onto its side and check the blade for
damage. Damaged or bent blades must be replaced.
Never attempt to bend a bent blade back to straight
again. Never mow the lawn with a bent or heavily
worn blade as this will cause vibrations and can lead
to further damage to the lawn mower.
m CAUTION! There is a risk of injury if you work with
a damaged blade.
Resharpening the blade
The blades can be resharpened with a metal file. In
order to avoid imbalance, the blade should be re-
sharpened by an authorized service workshop
Checking the oil level
m CAUTION! Never run the engine with no or too lit-
tle oil. This could cause severe damage to the engine.
Use only SAE30 engine oil.
Checking the oil level (Fig. 18):
• Stand the lawn mower on a flat level surface.
• Unscrew the oil dip stick (12) by turning anticlock-
wise, pull out and wipe. Insert the dip stick back in
the filling mount as far as the stop, but do not screw
back in.
• Pull out the dip stick (12) again and read off the oil
level while holding horizontally. The oil level must
be between the maximum and the minimum
Changing the oil (Fig. 23):
• Change the engine oil every year before the start of
the season when the engine is warm.
• Use only engine oil (SAE30).
• Empty the fuel tank (with a petrol suction pump)
• Place a flat oil drip tray in front of the mower (min.
volume 1 Litre).
• Remove the dipstick and tip over the mower until
the whole oil is run out into the oil drip tray.
• Fill up with engine oil as far as the top mark on the
dipstick (approx. 0.5 l).
• Important! Do not screw in the oil dipstick to check
the oil level – only insert it as far as the thread.
Dispose of the used oil in accordance with applicable
regulations.
Cleaning the belts (Fig. 17, 19):
• Remove the knife and the gear housing by loosen-
ing the screws out.
• Clean the elements of the transmission and the belt
once or twice a year with brush or compressed air.
• Screw the transmission housing and the knife on
again.

Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
Maintenance of the air filter (Fig. 20)
A soiled air filter will reduce the performance of the
engine because it will prevent enough air getting to
the carburetor. It is therefore imperative that regular
checks are made. The air filter should be checked
every 25 hours and cleaned if required. If the air is
very dusty the air filter should be checked more reg-
ularly.
Unclip the air filter cover and remove the sponge filter
element. To avoid objects falling into the air intake,
replace the air filter cover. (Fig. 20).
Important: Never clean the air filter with petrol or in-
flammable cleaning agents. Clean the air filter with
compressed air or simply by knocking out any soiling.
Maintenance of the spark plug (Fig. 21)
Check the spark plug for dirt and grime after 10 hours
of operation and if necessary clean it with a copper
wire brush. Thereafter service the spark plug after
every 50 hours of operation.
Pull off the spark plug boot with a twist. Remove the
spark plug (10) with a spark plug wrench.
Using a feeler gauge, set the gap to 0.75 mm( 0.030").
Refit the spark plug taking care not to overtighten.
Engine brake lever (Fig. 1)
The engine is equipped with a mechanical brake (3)
which has to be checked regularly. When releasing
the brake lever, the blade must come to a halt within
7 seconds. If this is not the case, the machine must
not be used. Contact an authorised specialist retailer.
Ensure that the machine is in a flawless condition for
its entire service life. Improper maintenance may lead
to life-threatening injuries.
Repairs
After any repair or maintenance work, check that all
safety-related parts are in place and in proper work-
ing order. All parts which may cause injury must be
kept where they are inaccessible to children or oth-
ers.

lation we are not liable for any damages caused by
